VEHICLE-AXLE.

SPECIFICATION forming part of Letters Patent No. 423,776, dated March. 18, 1890.

Application filed November 18,1889. Serial No. 330.682- (No model.)

To all whom] it may concern:

Be it known that we, JOHN A. JOHNSON and TARGE G. MANDT, residents, respectively, of Madison and Stoughton, in the county of Dane and State of Wisconsin, have invented cer tain new and useful Improvements in Axles for Vehicles; and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable IO others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, whichform a part of this specification, and in which Figure 1 is a side view of our improved '15 axle with the skeins complete and ready for use, but one of the nuts having been removed. Fig. 2 is a longitudinal sectional view of the same; and Fig. 3 is a sectional detail view, on an enlarged scale, of one end of the axle with the skein or thimble removed.

Like letters of reference denote correspon (1- ing parts in all the figures.

This invention relates to metallic axles for vehicles, made round and provided with metallic skeins or thimbles at their outer end;

and it has for its object to construct as an improved article of manufacture a metallic axle having skeins which may readily be removed when Worn out and which admits of g the easy and speedy substitution of newskeins,

and that in such a manner that the new skeins will when adjusted always and necessarily assume their proper working position relative to the axle.

With this object in View our improvement consists in the detailed construction and combination of parts of the axle-body proper and the skeins, substantially as will be hereinafter more fully described and claimed.

40 Reference being had to the accompanying drawings, the letter A denotes the axle proper, which is made round or cylindrical, of steel, iron, or other suitable metal. This axle, as will appear from the drawings, is perfectly 5 straight from end to end; but its extreme outer ends A are canted and reduced by cutting away both sides on a slant, as indicated at a, said canted and reduced ends being screw-threaded to adapt them to receive the nuts B, so that the inner ends of the nuts will bear up square against the outer ends of the skeins or thimbles (shown at O) and box B.

The skeins or thimbles are of the construction shown more clearly in Fig. 2 of the drawin gsthat is to say, they are cast hollow, with a recess D, and bored through longitudi- 11ally, but not centrallythat is to say, the bore E is made to fit the axle closely on a slant or incline corresponding to the pitch and gather which the Wheel is to have and nearer the under side of the skein than the upper, so that the skeins will be set at the proper angle relative to the body of the axle without the necessity of bending the ends of the latter, so that the axle may be left perfectly straight from one end to the other. This pitch or incline of the skeins O C corresponds to the pitch or slant of the reduced and threaded ends A A, which receive the nuts B B, so that the latter will always bear up true against the ends of their respective skeins and boxes.

The outer end of the bore E (denoted by the letter E) is threaded, so that the skein may be securely (yet removably)'fastened by screwing it upon the threaded endsb b of the axle. As an additional means of fastening, the shoulders or bearings F F, which are integral with and project rearwardly from the skeins, so as to bear against the under side of the axle in the usual manner, are recessed, as shown at f, so as to form a semi-cylindrical chamber surrounding the correspond ing portion of the axle on the under side, and aft-er the skein has been adjusted in its proper position upon the axle thischamber or recess f is filled with Babbitt metal or some other composition possessing the same qualities, by means of which (in addition to the threaded end of the axle) the skein is fastened and held securely in its position, or, if preferred, the bearings FF maybe left full in the metal and bored out when the skein is bored, so as to exactly fit the axle. At the same time the skein may readily be removed when worn, or if for any other reason itis desired to remove it, simply by knocking out or fusing the filling of Babbitt metal and then unscrewing the skein from its appropriate end of the axle. By this construction and combination of the axle and skeins itwill be seen that theformer v dinary intelligence can readily remove the old will last indefinitely, as there is no wear upon it, and no parts are weakened or strained by bending. Any farmer or other person of oron the part of the person putting on the skeins, which operation, therefore, does not require skilled labor.

Having thus described our invention, We claim and desire to secure by Letters Patent of the United States As an improved article of manufacture, a metallic axle for vehicles comprising the following elements in the specified combination, viz: a straight round axle having its extreme outer ends reduced, slanted downwardly by such reduction and threaded to receive the usual nuts, and the removable hollow skeins boredthrough slantingly and eccentrically, the outer part of the bore being threaded to adapt it to be screwed upon the threaded outer ing or packing of Babbitt metal or its equivalent' as an auxiliary means offastening, substantially as and for the purpose herein shown and set forth.

In testimony that we claim the foregoing as our own we have hereunto affixed our signatures in presence of two Witnesses.
